In such a case, one end of the interior part is engaged or abutted with the restricting part, and the clip is fitted to the clip mounting part while rotating the interior part with the engaging part or the abutting part as a fulcrum. They are attached to the mating member. In the interior part mounting structure that is attached to the mating member while rotating in this way, the opening of the clip mounting part is formed in an inverted U-shape that is open at the bottom in order to avoid interference with the rotation locus of the clip tip. The

  FIG. 3 is a cross-sectional view schematically showing an example of the mounting structure for interior parts as described above. One end side 12 a of the interior component 12 is regulated by another interior component 14 disposed at the upper part of the interior component 12, and the other end is disposed by an interior member 18 disposed below the interior component 12. Side 12b is regulated. In the mounting structure 2, the interior part 12 is attached to the mating member 16 accommodated in another interior part 14.

  A clip 20 is erected on the back surface of the interior part 12, and a clip mounting portion 22 corresponding to the clip 20 is formed on the mating member 16.

  As shown in FIG. 4, the clip 20 is an integrally molded part of a resin material, and once from a pair of abutment ribs 20 a erected from the back side of the interior part 12 and an intermediate part of the abutment ribs 20 a. It is composed of an elastically deformable engaging portion 20b that extends substantially horizontally and then widens and is connected to the tip portion to form a substantially rhombus shape. An engaging groove 20c is formed between the contact rib 20a and the engaging portion 20b. Reference numeral 20d denotes a positioning rib.

  The clip mounting portion 22 is a substantially U-shaped cylindrical portion whose opening 22a is open downward, and engaging projections 22b that fit into the engaging grooves 20c of the clip 20 are formed on both sides of the opening 22a. ing. Reference numeral 22e denotes a positioning groove into which the positioning rib 20d of the clip 20 is fitted.
